HOISTING-WAGON.

SPECIFICATION forming part of Letters Patent No. 753,888, dated March 8,1904.

Application led July 11, 1903. Serial No. 165,121.` (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, ALBERT E. JOHNSON, a citizen ofthe United States,residing at Northfield, in the-county of Rice and State of Minnesota,have invented new and useful Improvements in Hoisting-Wagons, of whichthe fol-4 hoisting position.

- novel construction,combination, and arrange-v ment of Apartshereinafter more fully described A stillfurther object is to employsimple mechanism for operating an apron mounted uponthe hoistingapparatus. Y

With the -above and other objects in view the invention consists inproviding a wagonframe which is pivoted to standards which are mountedupon the rear axle of the vehicle. Mechanism is provided whereby thestandards can be swung inward by the forward movement of the vehicle, soas to cause the body thereof to assume an inclined position. Means arealso provided whereby when the vehicle is drawn forward the apron uponthe wagonbody will be moved upward, so as to hoist any material whichmay be arranged-thereon.

The invention also consists in providing mechanism for automaticallyreturning the apron to normal or loweredv position after the dischargeof material therefrom.

The invention also consists .in the further and claimed, and illustratedin the accompanying drawings, showing the preferred form of myinvention, and in which- Figure 1 is a side elevation of my improvedhoisting mechanism. 'j Fig. 2 vis a longitudinal section therethrough.Fig. 3 vis a side elevation thereof, showing the body of the vehicle inan inclined position. Fig. 4 is a rear elevation of the standards andthe parts connected thereto, the body of the vehicle being reforwardportion of the apparatus. Fig. 6 is a perspectiveview of theclutch-operating.

bar, and Fig. 7 is a detail view of the bodysupporting standard of thedevice.

Referring to the figures by numerals of reference, 1` is the front axleof the vehicle, having traction-wheels 2 of any suitable construetionarranged thereon, and to this axle is secured a tongue 3, through whichthe. draftanimals are adaptedto be hitched in any suitable manner. Theupper surface ofthe rear portion of this tongue is provided withyarecessl, over which extends an apertured plate 5, and seated. withinthis recess and below the plate 5 is a ball 6, formed at the end of astem 7 which is integralwith a block 8. Rods' 9 extend from the cornersof the block and are bolted or otherwise secured in the forward portionof the frame 10vof the vehicle-body. This framev is formed of side beams11, and pivoted to these beams at points between'their ends arestandards 12, which are connectedv has traction-wheels 15 looselymounted there-l on, and revolublewith each wheel isa clutch member 16. Adrum 17 is loosely mounted on the axle adjacent each clutch member 16,and these drums have tapered ends 18, which project into the clutchmembers 16. Gears 19 are formed at the inner ends of the drums '17 andmesh with smaller gears 20,.which are secured .to shafts 21, vjournaledwithin the standards 12, and secured to the inner ends of -the shaftsare disks 22. A,rod 23 is eccentrically connected to each disk and has apiston24 at itsy other end which is slidably mounted within a cylinder25', secured to the inner face of lthe' adjacent'standard 12. Thiscylinder is closed at the ends for the purpose hereinafter more fullydescribed. To one'of the cross-strips 13 is pivoted a lever`26, to oneend'of which are pivoted oppositely-extend-v IOO lIo

in the upper ends of the standards 12. Pulleys 31 are journaled inbrackets 32 on the outer faces of the standards 12, near the pivotsthereof, and are substantially in alinement with the drums 17hereinbefore referred to.

A shaft 33 is journaled in brackets 34, secured to the lower surfaces ofthe side beams 11, and this shaft extends transversely of the body ofthe vehicle and is provided near each end with drums 34, to which aresecured the ends of cables 35, which are fastened at their other ends tobrackets 36, fastened to the lower ends of the standards 12. A drum 37is arranged at one end of the shaft 33 and outside the body of thevehicle, and secured to this drum is a cable 38, which extends over oneof the pulleys 31 to the drum'17 in alinement therewith. A ratchet 39 isformed'with drum 37 and a spring-pawl 40 serves to prevent the drum fromunwinding the cable. This pawl is preferably formed of acentrally-pivoted lever, the forward end of which is normally depressedby a coiled spring 41. A-lever 42 is arranged adjacent the pawl and hasa cam formed at one end and adapted to contact with and force the pawlinto engagement with the ratchet 39 when so desired.

A shaft 43 extends transversely of the body of the vehicle in a planeabove shaft 33, and upon this shaft are secured, preferably, two drums44, to which are secured the ends of cables 45, the opposite ends ofwhich are fastened to a compressing strip 46, slidably mounted upon rods47, which are secured to the inner faces of the side beams 11 and extendlongitudinally thereof. Uoiled springs y48 are mounted on the rods 47and are interposed between the compressing-strip 46 and blocks 49,arranged at the forward ends of the rods. Sprockets 50 are also securedto the shaft 43, and mounted thereon are chains 51, which are connected.by transversely-extending slats 52, forminga conveyer-apron. Thesechains 51 are also mounted on sprockets 53, j ournaled on a shaft 54,extending transversely of the body of the vehicle, near the rear endthereof. A board 55 is arranged adjacent the front end slat of theconveyer-apron and in a plane preferably at rightangles to the apron.

To one end of the shaft 43 is secured a drum 56, upon which is mounted acable 57, which extends over the other pulley 31 and to the remainingdrum 17. This drum has a ratchet revoluble therewith and normallyengaged by a spring-pawl 59, similar to the one heretofore described,and provided with an operatinglever 60, similar to the lever 42. Levers61 are fulcrumed at their lower ends to the forward ends of the sidebeams 11 of the vehiclebody, and the upper ends of these levers areconnected by a rod 62, which extends in front of the seat 63 at theforward end of the vehicle. Each lever 61 is connected, by means of acable 64, with one of the arms 28, said cable 65 being arranged withinthe guide-recess 30 of one of the standards 12 and fastened in one ofthe apertures 29.

In using the apparatus herein described the hay or other material to bestacked is placed upon the apron, which is normally in the positionshown in Figs. 1 and 2. The machine is then drawn forward, and whendesired the operator' presses forward upon one end of rod 62, so as toswing the lever 61 adjacent thereto and impart longitudinal movement tothe cable 64, which is connected to it and which is arranged at the leftside of the apparatus. This cable will serve to swing the arms 28 andthe lever 26, so as to press the end of one of the rods 27 into contactwith the gear 19, adjacent thereto, thereby forcing the tapered end 18of the drum 17 into frictional contact with the clutch member 16. Cable38 will thus be wound upon said drum, and the cables 35 will besimultaneously wound upon the drums 34. The standards 12 will thereforebe swung into position shown in Fig. 3 and the body ofthe vehicle raisedto an inclined position. By pressing the lever 42 forward the cam end ofsaid lever contacts with the spring-pawl 40 and forces it downward intoengagement with the ratchet 39 of drum 37, and the parts are thereforeprevented from returning to normal or lowered position until after thepawl has been released from the ratchet, when said parts will return bygravity. After the body of the vehicle has been raised at a desiredincline the lever 61, which has been pressed forward, will be allowed toreturn to normal position, and the traction-wheels are therefore free torotate without changing the positions of the parts. After reaching theplace at which the material is to be stacked the vehicle is turnedaround, so as to bring the rear end thereof over theV stacking-point,and during such movement the other lever 61 is pressed forward, so as tothrow the clutch of the other drum 17 into operation, thereby windingthe cable 57 and causing drums 44 to rotate and Wind the cable 45. Asthese cables are connected to the compressing-strip 46,said strip willbe drawn downward and compress the springs 48. Simultaneous with thismovementl the chains 51 will be moved upon the sprockets 5() and 53 andthe conveyer-apron will be carried upward, thereby discharging materialover the end of the vehicle-body. The spring-pawl 59 of ratchet 58 willprevent the compressed springs 48 from expanding until after all thematerial upon the apron has been removed. When it is desired to returnthe apron to its normal position, the lever 60 is drawn inward, so as torelease the spring-pawl 59 from ratchet 58 and the springs 48 thereforeexpand and press the strip 46 upward on rods 47 and cause the cables 45to unwind fromdrums 44. Cable 57 will therefore be wound simultaneouslyupon drum 56 and unwound from the drum 17, to which it is secured. Itwill of course be understood that as soon as the` apron IOO IIO

lvhasbeen raised a desired distance the lever 61 will be released, so astov permit the independent movement of the parts in relation to thetraction-wheels connected to their drum 17. .By providing cylinders 25and the reciproeating pistons 24 the rotation ofthe various drums of thedevice is retarded, and injury to the parts `as a result of suddenreturn to normal position `is thus prevented... Inthe foregoingdescriptiomI have shown the preferredform of my invention; but Ido notlimit myself thereto,l as I am aware that modications may be madetherein withoutdeparting from-the; spiritfor sacrificing the adi 5vantages thereof, and I therefore reserve the right to make such changesand alterations as may fairly fall within the scope of my invention. vHaving thus fully describedthe invention, 2o what I claim as new,anddesire. to. secureA by *Letters Patent, isl l.
